Vision

LLMs are style transfer engines. The real reasoning should come from a deterministic logic layer underneath. Instead of teaching statistical models to do math, use systems that already solved it.

Key Insight from Brainstorm

"I would rather start with Wolfram, like some open source version of Wolfram, and then just tag on the conversational LLM on the edges where it makes sense."

"We've already solved logical reasoning with mathematics and computers, and now we've gone backwards trying to teach LLMs how to do math correctly. That's a huge waste of time."

Architecture: "Soft Brain + Mechanical Brain"

Mechanical Brain: Deterministic logic engine (SymPy, Z3 theorem prover, Lean 4, or Prolog-style reasoner)
Soft Brain: Hermes 4 conversational layer for style transfer, personality, and natural language interface
LLM calls the logic engine for any reasoning/math, logic engine returns verified results, LLM presents them conversationally

Candidates to Evaluate

SymPy — symbolic math (Python, easy to integrate)
Z3 (Microsoft) — SMT solver, formal verification, constraint solving
Lean 4 — proof assistant, formal verification
SWI-Prolog — logic programming, rule-based reasoning
Maxima — open-source computer algebra (closest to Wolfram)

Acceptance Criteria

Evaluate at least 3 deterministic engines for Hermes Agent integration
Build a tool-calling bridge: Hermes Agent → logic engine → verified answer
Hermes Agent defers all math/logic to the engine, uses LLM only for presentation
Sovereignty check: must run fully local, no cloud dependencies

Feeds into DPO alignment: preference pairs should favor "verified logic" over "hallucinated reasoning"
The "truth engine" that Timmy checks his decisions against

Closing during the 2026-03-28 backlog burn-down.

Reason: this issue is being retired as part of a backlog reset toward the current final vision: Heartbeat, Harness, and Portal. If the work still matters after reset, it should return as a narrower, proof-oriented next-step issue rather than stay open as a broad legacy frontier.
